MOP-WRINGER.

To all whom it may concern:

Be it known that I, CORNELIUS JOHN ALLEN, a citizen of the UnitedStates, residing at St. Louis, State of Missouri, have invented a newand useful Mop-\Vringer, of which the following is a specification.

My invention relates to mop wringers and has for an object to provide adevice of this character which will have no brackets or like complicatedbearings to get out of order, the parts being few in number, strong instructure, and durable and effective in operation.

Another object is to provide a device of this character in which themovable roller frame is so fulcrumed on the stationary roller frame thata powerful, downward and inward pressure is imparted by the foot leverto the movable roller frame.

A further object is to provide a device of this character that, whenremoved from a pail, can be collapsed in a flat compact form quickly andeasily.

With these and other objects in view, which will appear in the followingspecification and be set forth in the claim, my invention embraces thestructure illustrated in the accompanying drawing, in which, is shown aperspective view of a combined pail and mop wringer constructed inaccordance with my invention, showing the movable roller dotted in finalposition.

At this point it may profitably be stated that both sides of the deviceare of the same construction, with the exception that but one spring 24,hereinafter described, is employed.

In a more detailed description of my invention, in which like charactersof reference designate similar parts in the views shown, 1 designates apail or bucket of the usual kind, to one of the lateral sides of whichis attached an angle iron foot piece 2, the lateral flange 3 of whichrests on the floor and forms a means for holding the pail stationarythereon when the mop wringer is in operation. Attached to the oppositesides of the pail is the stationary roller frame which consists of apair of parallel side bars 4: positioned in inclined relation to thevertical aXisof the pail, having their upper ends connected by a rodforming a shaft 5 for a rotatable roller 6. This roller may be made ofwood, fiber, rubber or similar material and forms what willSpecification of Letters Patent.

hereafter be termed the stationary roller of the device. The stationaryframe may be secured to the pail in any desired manner, but in thisinstance for simplicity in construction the connection is made by bolts7 and 8 passed through the opposite ends of the side bars and engagingregistering openings in the walls of the pail, each upper bolt 7 havinga screw threaded shank carrying a nut 9 adapted to bear against theouter surface of the side bar and hold the same securely in position,the lower bolts 8 being considerably longer than the upper bolts, thepurpose of which will presently appear, and each terminating in a screwthreaded end carrying a nut 10.

Pivoted on the stationary frame and normally held inclined thereto isthe movable roller frame comprising a pair of parallel side bars 11disposed on opposite sides of the pail and connected at their upper endsby a rod constituting a shaft 12 for a roller 18 which is similar inconstruction to and adapted to work in conjunction with the stationaryroller and will be termed the movable roller ofthe device. The lowerends of the side bars are pivotally connected to the stationaryframeabove the lower end thereof by means of bolts 14, the shanks of whichpass through registeringopenings in the stationary and movable side barsand terminate in screw threaded ends carrying nuts 15 adapted to bearupon the outer surfaces of the movable side bars and retain the same inplace.

Secured to each of the movable side bars 11 intermediate the endsthereof is a link 16, one end of said link being pivotally connected tothe side bar by means of bolt 17 carrying a nut 18 to retain a link inplace, the lower end of each link being pivotally connected to a footlever 19. The foot 1ever 19 consists essentially of a U-shaped metalyoke terminating in parallel arms 20, and is preferably made of springmaterial to give a yielding pressure to the device to prevent theracking or injuring of the parts when in operation. The terminals of theyielding arms 20 are provided with openings to engage the beforementioned extended shank of the lower securing bolts 8, and are heldspaced from the sides of the stationary side bars by washers 21. It willthus be seen that the foot lever is pivotally connected to thestationary frame at a point below the pivotal connection of the movableframe and operates through the medium of the connecting links 16 to rockthe movable frame and place the roller carried thereby in cooperativerelation with the roller carried by the stationary frame.

Positioned intermediate the ends of the yielding arms are bolts 22 whichengage registering openings in the ends of the links 16 and serve topivotally connect the links to the arms. The bolts 22 terminate in screwthreaded ends to carry nuts 28. Between a nut 23 and the adjacent link16 is secured one of the terminals of the coil spring 24, the oppositeterminal 25 being engaged around the shank of the upper securing bolt 7and held secured between the nut 9 carried thereon and the lateral faceof the stationary side bar 4:. The spring when in normal positionoperates to hold the rollers 6 and 13 spread apart so that a mop mayreadily be inserted t-herebetween and when the foot lever is depressedthe spring will be put under an increased tension to return the rollersto their initial position as soon as the foot lever is released. Atreadle 26 of any desired construction is secured to the foot lever,preferably at the center thereof, and upon which the foot is placed todepress the foot lever and bring the roller in contact.

The device when removed from the pail may be collapsed into a flatcompact form by removing the nuts 18 that retain the connecting links 16to the movable frame. The links may now be extended forwardly in thedirection of the movable roller, the movable roller moved into contactwith the stationary roller, and both laid back upon the foot lever inwhich position the device is in flat form ready for shipment or storage.

From the foregoing description, taken in connection with theaccompanying drawing, it is thought that the construction and operationof the invention will readily be understood without a more extendedexplanation, it being understood that variouschanges in the form,proportion and minor details of construction may be made withoutsacrificing any of the advantages or departing from the spirit of theinvention.

What is claimed is As an article of manufacture an attachment for pailsand the like, including straight parallel side bars, a roller interposedbetween the bars at one end and mounted for rotation, means forattaching the bars to a pail, straight parallel side bars pivotallyconnected to the first mentioned bars, a roller interposed between andmovable with said pivoted bars, a yoke pivotally connected to the sidebars at those ends thereof farthest removed from the roller carried bysaid bars, said yoke having all portions disposed in the same plane, aspring interposed between and connecting one side bar with one side ofthe yoke, and a link connecting each side of the yoke to one of thepivoted bars, the links being detachably connected to the pivoted barsand being straightfrom end to end, the side and pivoted bars, the linksand the yoke being foldable together.

In testimony that I claim the foregoing as my own, I have heretoa'flixed my signature in the presence of two witnesses.
